correct and for the third time, I am asking you what -(-4) is equal to?

openstudygirl2 · Answer

i dont know ?

zzr0ck3r · Answer

I wrote this above



hint-(-a)=a

zzr0ck3r · Answer

so what is -(-4)?

openstudygirl2 · Answer

does it change so the -4 is now positive 4

zzr0ck3r · Answer

I would not think of it like that. It is more like $-(-4)=-1\times (-1\times 4)=-1\times -4\=4$

openstudygirl2 · Answer

ok

zzr0ck3r · Answer

nothing is "changing" but anyway...

ok back to your question

-2-(-4)=-2+4
